Green Computing Practice

Electrical Conservation Tips:

• Turn the computer off overnight and on weekends;
• Wait until ready to use the PC before turning it on;
• If the computer is going to be inactive for more than 16 minutes, consider turning it off. After this time, the energy needed to run the computer outweighs the start-up energy;
• Do not turn on the printer until ready to print, even an idle printer consumes energy;
• Try to schedule computer-related activities to do them all at once, keeping the computer off at other times;
• If spending a large amount of time at the computer, consider reducing the light level in your office. This may improve cathode ray tube screen visibility as well as save energy.

Paper Conservation Tips:

• Use "paperless" methods of communication such as electronic mail (e-mail) and fax modems. Also, do not print out copies of e-mail messages unless necessary;
• Use smaller font sizes and decrease the spacing between lines, or reformat to keep the document to as few pages as possible;
• Review documents on the screen instead of printing a draft. If you must print a draft, use the blank back side of used sheets;
• Use a printer that can print double-sided documents. When making copies, use double-sided copying;
• The U-M buys and uses recycled-content paper when possible. Look for papers with 50 - 100 percent post-consumer waste and non-chlorine bleached. Also, recycle paper when done.
• Store information on diskettes rather than in "hard copy" format. A single high-density 3.5 inch floppy disk can hold the equivalent of 750 sheets of paper, about one and a half reams. Also, be sure to reuse disks that contain outdated information.

Purchasing and Use of Equipment:

• Printer toner cartridges can be refilled, rebuilt and reused. Many manufacturers will take a spent cartridge, refurbish it, refill it, and return it for about half the price of buying a new one;
• Determine whether you can upgrade your existing equipment rather than purchasing new equipment;
• Donate an old computer to a school or charity; if it is permanently out of order, give it to a computer recycling facility instead of discarding in a landfill;
• Only buy a monitor as large as you really need; a 17 inch monitor uses 40 percent more energy than a 14-inch monitor. Also, the higher the resolution, the more energy it needs;
• Consider purchasing an ink jet printer instead of a laser printer. Although they are a little slower, they use 80-90 percent less energy;
• Request recycled or recyclable packaging from your vendor;
• Buy soy or non-petroleum based inks. These printer inks are made from renewable resources, require fewer hazardous solvents, which translates to fewer air emissions, and in many cases produce brighter, cleaner colors;
• Try to buy energy efficient products such as those bearing the Energy Star Logo. The Energy Star Program was started by the Environmental Protection Agency (EPA) to encourage the production and use of energy-efficient equipment. In accordance with the EPA's voluntary guidelines, leading computer manufacturers are now producing equipment that can automatically power down to a "sleep mode" to save energy when not in use. They also use up to 30 percent less energy when running than conventional equipment. These added capabilities do not increase price or decrease performance.

Green Computing Practice

· Reducing Paper Waste- Minimize the number of hard copies and paper drafts you make. Instead of printing, save information to disks.

· Recycle waste paper- Buy and use recycled paper in your printers and copiers.

· Reusing and recycling- CU generates thousands of spent printer toner and ink jet cartridges and batteries a year. Instead of tossing these in the garbage, they can be recycled, saving resources and reducing pollution and solid waste.

· Purchasing recommendations -Environmentally responsible computer use implies not buying new equipment unless there is a demonstrated need

· Network and share printers- Consider leasing equipment as an alternative to purchasing. Leased equipment is typically refurbished or recycled, and packaging is reduced.

Green Computing Practice

· Reduce carbon emissions by simply turning off their monitors, or shutting down their computer when they are away.

· always better to shut the computer off if the plan not to use it for a stretch of time

· Night-time remote backup service, a process that would eliminate the need to leave machines overnight.

· Power the Printer off after office hours, or whenever they are not in use.

In order to adopt the concept of “Campus Green Computing”, maybe the school should conduct seminars to the faculty and students. Although each one knows about it, they did not always apply it to themselves. To those who know it already, he/she can also give advice to his/her friends. So, when everyone knows about how important the concepts of “Campus Green Computing” everyone can apply to it.
